Description

Stand der TechnikState of the art

Die Erfindung betrifft einen Wagen zur Abstützung eines Erntevorsatzes, wobei der Wagen ein Gestell und mindestens ein sich vom Gestell nach unten erstreckendes Rad aufweist und das Gestell zur Abstützung des Erntevorsatzes und zur Gewichtsentlastung der vorderen Räder einer selbstfahrenden Erntemaschine bei einer Straßenfahrt lösbar an dem an der Erntemaschine angebrachten Erntevorsatz befestigbar und zum Erntebetrieb auf einem Feld vom Erntevorsatz trennbar ist.The invention relates to a carriage for supporting a header, wherein the carriage comprises a frame and at least one extending from the frame down the wheel and the frame for supporting the header and to relieve the weight of the front wheels of a self-propelled harvester in a road trip solvable on the at the Harvester mounted harvesting attachment attachable and separable to the harvesting operation on a field from the header.

An selbstfahrenden Erntemaschinen finden Erntevorsätze zum Abernten und Einbringen von Erntegut Verwendung. Aufgrund von Leistungssteigerungen der Erntemaschinen in jüngerer Zeit werden immer breitere Erntevorsätze verwendet, die eine relativ große Masse aufweisen. Während Schneidwerke für Mähdrescher gewöhnlich in sich starr sind und zum Straßentransport vom Mähdrescher getrennt und auf einem Transportwagen abgelegt werden, werden Maispflücker für Mähdrescher und Maisgebisse für Feldhäcksler in der Regel klappbar ausgeführt. Es gibt jedoch auch klappbare Schneidwerke für Mähdrescher. Zum Straßentransport werden äußere Seitenteile der Erntevorsätze in eine Transportstellung verschwenkt, in der Regel nach oben oder innen. Sie bleiben beim Straßentransport an der Vorderseite der Erntemaschine befestigt. Dabei stellt sich die gesetzlich zulässige Gewichtsbelastung der Vorderräder der Erntemaschine bei den zunehmend breiter und schwerer werdenden Erntevorsätzen als problematisch dar.Harvesting attachments for harvesting and harvesting crops are used on self-propelled harvesting machines. Due to recent increases in performance of harvesters, ever wider crop headers are being used which have a relatively large mass. While combine harvesters are usually rigid in themselves and are separated from the combine for road transport and stored on a trolley, corn pickers for combine harvester and corn forage for forage harvesters are usually made hinged. However, there are also hinged cutting units for combine harvesters. For road transport outer side panels of harvesting headers are pivoted into a transport position, usually upwards or inwards. They remain attached to the front of the harvester for road transport. Here, the legally permissible weight load of the front wheels of the harvester is problematic in the increasingly wide and heavier harvest headers.

In der EP 1 046 329 A wurde vorgeschlagen, ein zusätzliches Rad zur Abstützung des Erntevorsatzes bereitzustellen, das beim Straßentransport der Erntemaschine in Bodenkontakt gebracht werden kann. Dadurch erhält man eine zusätzliche Abstützung, die eine Einhaltung der gesetzlichen Vorschriften erleichtert oder ermöglicht. In einer Ausführungsform ist das zusätzliche Rad an einem separaten Wagen angebracht, der unter den Erntevorsatz schiebbar und dort befestigbar ist.In the EP 1 046 329 A It has been proposed to provide an additional wheel for supporting the header, which can be brought into contact with the ground during road transport of the harvesting machine. This provides an additional support that facilitates or allows compliance with legal requirements. In one embodiment, the additional wheel is mounted on a separate carriage which is below the header pushed and fastened there.

Falls eine Erntemaschine mit einem an ihrer Vorderseite befestigten Erntevorsatz auf einer öffentlichen Straße fahren soll, sind in einigen Ländern Schutzeinrichtungen am Erntevorsatz anzubringen, um geltende Sicherheitsvorschriften einzuhalten. So sind an der Vorderseite des Erntevorsatzes reflektierende Warntafeln anzubringen und die Seitenflächen oder, falls vorhanden, die hochgeschwenkten Seitenteile des Erntevorsatzes mit Seitenplanen abzudecken. Außerdem sind am Erntevorsatz Beleuchtungseinrichtungen zu montieren. Im Stand der Technik, wie er auch in der EP 1 046 329 A zeichnerisch dargestellt ist, werden diese Schutzeinrichtungen jeweils lösbar am Erntevorsatz befestigt. Neben der Anbringung des Erntevorsatzes am Wagen hat der Bediener der Erntemaschine demnach noch die Anbringung der Schutzeinrichtungen zur Aufgabe, die vor dem nächsten Erntevorgang auch wieder abzunehmen sind. Diese Arbeiten erweisen sich als relativ zeitaufwändig.If a harvester is to travel on a public road with a header fixed to its front, in some countries guards shall be attached to the header in order to comply with applicable safety regulations. Thus, at the front of the header are to install reflective warning signs and cover the side surfaces or, if present, the swung-up side parts of the header with side tarpaulins. In addition, lighting equipment must be mounted on the header. In the state of the art, as he also in the EP 1 046 329 A is shown in the drawing, these guards are each releasably attached to the header. In addition to the attachment of the header on the car, the operator of the harvester therefore still has the attachment of the protective devices to the task, which must be removed before the next harvesting process again. This work proves to be relatively time consuming.

Aufgabe der ErfindungObject of the invention

Die der Erfindung zu Grunde liegende Aufgabe wird darin gesehen, einen Wagen zur Abstützung des Erntevorsatzes bei der Straßenfahrt bereitzustellen, der eine Verkürzung der Umrüstzeit zwischen einer Konfiguration zur Straßenfahrt und einer Konfiguration zur Ernte ermöglicht.The object underlying the invention is seen to provide a carriage for supporting the header during road travel, which allows a shortening of the changeover time between a configuration for driving on the road and a configuration for harvesting.

Diese Aufgabe wird erfindungsgemäß durch die Lehre des Patentanspruchs 1 gelöst, wobei in den weiteren Patentansprüchen Merkmale aufgeführt sind, die die Lösung in vorteilhafter Weise weiterentwickeln.This object is achieved by the teaching of claim 1, wherein in the other claims features are listed, which further develop the solution in an advantageous manner.

Es wird vorgeschlagen, an dem Gestell des Wagens, der zur Abstützung des an der Vorderseite der Erntemaschine angebrachten Erntevorsatzes bei einer Straßenfahrt dient, auch die Schutzeinrichtung zur Abdeckung des Erntevorsatzes anzubringen.It is proposed to attach to the frame of the car, which is used to support the mounted on the front of the harvester header in a road trip, and the protective device to cover the header.

Auf diese Weise erreicht man eine Einhaltung der Sicherheitsbedingungen bei der Straßenfahrt, ohne dem Bediener einen größeren Zeitaufwand zur Anbringung der Schutzeinrichtung aufzuerlegen. Die am Wagen befestigte Schutzeinrichtung kann nicht verloren gehen oder vergessen werden.In this way, one achieves compliance with the safety conditions when driving on the road without imposing a greater amount of time on the operator to install the safety guard. The protective device attached to the car can not be lost or forgotten.

Die Schutzeinrichtung umfasst in der Regel Warntafeln, die sich im Straßenfahrzustand an der Vorderseite des Erntevorsatzes vertikal und quer zur Fahrtrichtung erstrecken. Sie sind in der Regel reflektierend ausgeführt und mit Mustern versehen. Zu ihrer Anbringung dient vorzugsweise ein am Gestell befestigter Träger, der horizontal und quer zur Vorwärtsrichtung verläuft. Er befindet sich, wenn das Gestell am Erntevorsatz montiert ist, an der Vorderseite des Erntevorsatzes.The protective device usually includes warning panels that extend in the road driving condition on the front of the header vertically and transversely to the direction of travel. They are usually reflective and patterned. For their attachment is preferably used a support fixed to the frame, which extends horizontally and transversely to the forward direction. It is located at the front of the header when the frame is mounted on the header.

Der erwähnte Träger kann zusätzlich oder alternativ zur Befestigung eines vertikalen Haltepfostens Verwendung finden. Der Haltepfosten trägt eine Seitenplane zur Abdeckung der Seitenfläche des Erntevorsatzes. Die Seitenplane ist ebenfalls Bestandteil der Schutzeinrichtung und wird bei der Straßenfahrt mit ihrem rückwärtigen Ende an der Rückseite des Erntevorsatzes festgezurrt. Dazu kann das rückwärtige Ende der Seitenplane mit einer Stange verbunden sein, die ihrerseits mit federbelasteten Haken ausgestattet ist, die am Erntevorsatz abnehmbar angebracht werden und zur Straffung der Plane dienen. Die erwähnten Seitenplanen werden an beiden Seiten des Erntevorsatzes angebracht. Es wäre im Übrigen auch denkbar, die Seitenplanen und Haltepfosten durch in sich starre, fest mit dem Gestell verbundene Seitenwände zu ersetzen. Dadurch erspart man sich das Anbringen und Abnehmen der rückwärtigen Enden der Seitenplanen vom Erntevorsatz, allerdings auf Kosten des Gewichts.The mentioned carrier may additionally or alternatively be used for fastening a vertical holding post. The support post carries a side curtain to cover the side surface of the header. The side tarpaulin is also part of the guard and is lashed on the road with its rear end at the back of the header. For this purpose, the rear end of the side tarpaulin can be connected to a rod, which in turn is equipped with spring-loaded hooks, which are removably attached to the header and serve to streamline the tarpaulin. The mentioned side tarpaulins are attached to both sides of the header. Incidentally, it would also be conceivable to replace the side panels and retaining posts with rigid side walls fixed to the frame. This avoids the attachment and removal of the rear ends of the side panels of the header, but at the expense of weight.

Die Schutzeinrichtung umfasst weiterhin Beleuchtungsmittel in Form nach vorn strahlender, weißer Lampen und/oder gelber Blinkleuchten. Auch die Beleuchtungsmittel sind zweckmäßigerweise am Gestell befestigt. Ein Anschlusskabel zur Stromversorgung der Beleuchtungsmittel kann an einer Seitenplane befestigt sein. Am rückwärtigen Ende des Anschlusskabels befindet sich ein Stecker, der in eine komplementäre Buchse an der Erntemaschine eingesteckt werden kann.The protective device further comprises lighting means in the form of forward-looking, white lamps and / or yellow flashing lights. The lighting means are suitably attached to the frame. A connection cable for powering the lighting means can be attached to a side tarpaulin be attached. At the rear end of the connection cable is a plug that can be plugged into a complementary socket on the harvester.

Falls die Erntemaschine sich nach dem Ende eines Erntevorgangs in einer größeren Entfernung vom Wagen befindet, der zu Beginn der Ernte am Rand eines Felds abgestellt wurde, kann es sinnvoller sein, den Wagen zur Erntemaschine zu transportieren, als die Erntemaschine zum Wagen zu fahren. Das Gestell des Wagens wird aufgrund des Trägers mit den daran angebrachten Elementen der Schutzeinrichtung allerdings relativ voluminös. Der Transport des Wagens, beispielsweise auf einem Anhänger für einen PKW oder einen Traktor, wird vereinfacht, wenn der Träger in eine kompakte Transportposition verbringbar ist. Dazu kann er sich aus drei Elementen zusammensetzen, von denen ein mittleres Element fest am Gestell befestigt ist, während die äußeren Elemente um vertikale Achsen verschwenkbar an den äußeren Enden des mittleren Elements verbunden sind. Die Elemente sind zumindest in der Position, in der sie zum Straßentransport des Erntevorsatzes in einer Linie zueinander ausgerichtet sind, arretierbar. Die äußeren Elemente werden zum Transport um die vertikalen Achsen verschwenkt, vorzugsweise nach hinten, und der Wagen kann leicht und kompakt verladen und transportiert werden. Es wären auch andere Möglichkeiten zur schwenkbaren Anbringung des Trägers denkbar: so könnten zwei jeweils eine Hälfte des Trägers definierende, einklappbare Elemente direkt am Gestell angebracht werden, oder auf jeder Seite des Gestells können zwei einklappbare Elemente vorhanden sein.If, after the end of a harvesting operation, the harvester is located at a greater distance from the car parked at the edge of a field at the beginning of the harvest, it may be more convenient to transport the cart to the harvester than to drive the harvester to the cart. The frame of the car, however, is relatively bulky due to the carrier with the attached elements of the protective device. The transport of the car, for example on a trailer for a car or a tractor, is simplified when the carrier can be brought into a compact transport position. For this purpose, it can be composed of three elements, of which a central element is fixedly secured to the frame, while the outer elements are pivotally connected about vertical axes at the outer ends of the central element. The elements are at least in the position in which they are aligned for road transport of the header in a line to each other, lockable. The outer elements are pivoted for transport about the vertical axes, preferably to the rear, and the car can be easily and compactly loaded and transported. Other possibilities for pivotally mounting the carrier would also be conceivable: two folding elements each defining one half of the carrier could be mounted directly on the frame, or two retractable elements could be present on each side of the frame.

Da an landwirtschaftlichen Erntevorgängen in der Regel Traktoren beteiligt sind, um das Erntegut einer Lagerstelle zuzuführen, bietet es sich an, auch einen Traktor zum Einzeltransport des Wagens zu nutzen. Um das Verladen auf einen Anhänger zu ersparen, weist das Gestell des Wagens in einer bevorzugten Ausführungsform Befestigungsmittel auf, die mit einer Dreipunktaufnahme oder einer anderen geeigneten Schnittstelle eines Traktors verbunden werden können. Der Traktor wird somit bei Bedarf zur Lagerstelle des Wagens gefahren, die Dreipunktaufnahme oder andere Schnittstelle wird mit dem Gestell verbunden und der Traktor mit dem Wagen schließlich zur Erntemaschine gefahren.Since tractors are usually involved in agricultural harvesting operations in order to feed the crop to a storage location, it makes sense to use a tractor for individual transport of the car. In order to avoid loading onto a trailer, in a preferred embodiment, the frame of the carriage has attachment means that can be connected to a three-point hitch or other suitable interface of a tractor. The tractor will thus if necessary, driven to the bearing of the car, the three-point or other interface is connected to the frame and the tractor with the car finally moved to the harvester.

In der Figur 1 ist der Einzugskanal 30 einer landwirtschaftlichen Erntemaschine 10 (s. Figur 2) in der Art eines selbstfahrenden Feldhäckslers schematisch dargestellt. Die Erntemaschine 10 baut sich auf einem Rahmen 12 auf, der von vorderen angetriebenen Rädern 14 und rückwärtigen lenkbaren Rädern (nicht gezeigt) getragen wird. Die Bedienung der Erntemaschine 10 erfolgt von einer Fahrerkabine 18 aus, von der aus ein Vorsatz 20 einsehbar ist. Mittels eines Erntevorsatzes 20 vom Boden aufgenommenes Gut, z. B. Mais, wird bei der Ernte über ein Einzugsgehäuse 30 einer nicht eingezeichneten Häckseltrommel im Innern der Erntemaschine 10 zugeführt, die es in kleine Stücke häckselt und es einer (ebenfalls nicht eingezeichneten) Fördervorrichtung aufgibt. Das Gut verläßt die Erntemaschine 10 zu einem nebenher fahrenden Anhänger über einen drehbaren Austragschacht 28. Zwischen der Häckseltrommel und der Fördervorrichtung kann eine nicht eingezeichnete Nachzerkleinerungsvorrichtung angeordnet sein. Obwohl die Erfindung hier an einem Feldhäcksler dargestellt wird, kann sie auch an beliebigen anderen selbstfahrenden Erntemaschinen wie Mähdreschern mit zugehörigen Erntevorsätzen, wie Schneidwerken oder Maispflückern, Verwendung finden. Im Folgenden beziehen sich Richtungsangaben, wie vor, hinter, seitlich und oberhalb, auf die Vorwärtsrichtung der Erntemaschine 10 und des Erntevorsatzes 20, die in den Figuren 1 und 2 nach links verläuft.In the FIG. 1 is the intake duct 30 of an agricultural harvester 10 (s. FIG. 2 ) in the manner of a self-propelled forage harvester shown schematically. The harvester 10 is built on a frame 12 supported by front driven wheels 14 and rear steerable wheels (not shown). The operation of the harvesting machine 10 is carried out by a driver's cab 18, from which a header 20 is visible. By means of a header 20 picked up from the ground Good, z. As corn is fed at harvest over a feeder housing 30 a not marked chopper drum inside the harvester 10, which chops it into small pieces and gives it a (also not shown) conveyor. The crop leaves the harvester 10 to a trailer traveling alongside a rotatable discharge shaft 28. Between the cutterhead and the conveyor, a not shown Nachzerkleinerungsvorrichtung can be arranged. Although the invention is shown here on a forage harvester, it can also be used on any other self-propelled harvesters such as combines with associated harvesting attachments, such as cutters or corn pickers. In the following direction, as before, behind, laterally and above, refer to the forward direction of the harvester 10 and the header 20, which in the FIGS. 1 and 2 goes to the left.

Zum Aufnehmen des Ernteguts dient der Erntevorsatz 20, der in Vorwärtsrichtung an der Frontseite des Einzugsgehäuses 30 der Erntemaschine 10 befestigt ist. Der Erntevorsatz 20 ist in der dargestellten Ausführungsform (s. insbesondere Figur 5) ein an sich bekanntes Maisgebiss. Anstelle der dargestellten, in sich starren Ausführungsform, die aufgrund der 3 m nicht überschreitenden Arbeitsbreite nicht in eine Straßenfahrstellung mit reduzierter Breite verschwenkbar ist, könnte auch eine ebenfalls an sich bekannte, mit zum Straßentransport nach oben schwenkbar an einem Mittelteil befestigten Außenteilen ausgestattete Ausführungsform Verwendung finden. Am Erntevorsatz 20 sind in der vorliegenden Ausführungsform vier Einzugs- und Mähtrommeln 32 angebracht. Die Einzugs- und Mähtrommeln 32 ziehen im Betrieb die Stängel des Mähguts in aufrechter Stellung ein, schneiden sie ab und führen sie dem Einzugsgehäuse 30 und anschließend der Häckseltrommel der Erntemaschine 10 zu.To pick up the crop, the harvesting attachment 20, which is attached in the forward direction on the front side of the feed housing 30 of the harvester 10 is used. The header 20 is in the illustrated embodiment (see in particular FIG. 5 ) a known maize header. Instead of the illustrated, inherently rigid embodiment, which is not pivotable due to the 3 m not exceeding working width in a road driving position with reduced width, could also be a known per se, equipped with the road transport upwards pivotally mounted on a central part outer parts equipped embodiment use , At harvest header 20 four feed and mowing drums 32 are mounted in the present embodiment. The intake and mowing drums 32 In operation, pull the stalks of the crop in an upright position, cut them off and feed them to the intake housing 30 and then to the chopper drum of the harvester 10.

Der Erntevorsatz 20 umfasst einen Trägerrahmen, der einen unteren Querträger 42 und einen oberen Querträger 44 aufweist. Der untere Querträger 42 erstreckt sich unten an der Rückseite des Erntevorsatzes 20. Der obere Querträger 44 erstreckt sich in seitlicher Richtung oberhalb des Einlasses des Einzugsgehäuses 30 über dessen Breite. Er ist mit hakenförmigen Tragelementen 50 verbunden (s. Figur 1), die von komplementären Tragelementen 52 des Einzugsgehäuses 30 untergriffen werden und zur Befestigung des Erntevorsatzes 20 an der Erntemaschine 10 dienen. Er ist durch sich vertikal erstreckende Träger 54 und Verbindungsbleche 56 mit dem unteren Querträger 42 verbunden.The header 20 includes a support frame having a lower cross member 42 and an upper cross member 44. The lower cross member 42 extends at the bottom at the rear of the harvesting attachment 20. The upper cross member 44 extends in the lateral direction above the inlet of the feeder housing 30 over its width. It is connected to hook-shaped support elements 50 (s. FIG. 1 ), which are engaged by complementary support members 52 of the feed housing 30 and serve to attach the header 20 to the harvester 10. It is connected to the lower cross member 42 by vertically extending beams 54 and connecting plates 56.

In der Figur 1 liegt der Erntevorsatz 20 auf einem Wagen 60 auf, der zur Abstützung des Erntevorsatzes 20 bei der Straßenfahrt dient. Der Wagen setzt sich aus einem Gestell 62 und einem Rad 64 zusammen. Das Gestell 62 umfasst ein fächerartig aufgespreiztes Rückteil 66, das über etwa vertikal verlaufende Streben 68 mit einem Vorderteil 70 verbunden ist und unterhalb des Vorderteils 70 angeordnete Radhalterungen 72, zwischen denen das Rad 14 um eine sich seitlich erstreckende Achse drehbar gelagert ist. An der dem Rückteil 66 zugewandten Seite des Vorderteils 70 befindet sich eine Wagenpositionierungseinrichtung 74, die eine taschen- oder tütenartige, in der Figur 1 nach rechts gerichtete Öffnung aufweist, deren Unterseite sich schräg nach hinten und unten bis zum Rückteil 66 hinunter erstreckt. Die Wagenpositionierungseinrichtung 74 dient zur selbsttätigen Ausrichtung des Wagens 60 gegenüber dem Erntevorsatz 20, indem eine Teilerspitze 71 des Erntevorsatzes 20 darin aufgenommen wird (s. Figur 5). Rückwärtige Stützen 76 stützen den Rückteil 66 des Gestells auf dem Erdboden ab. Das Rad 64 ist in der dargestellten Ausführungsform um eine sich etwa vertikal erstreckende Drehachse 78 nachlaufend lenkbar am Gestell 62 angelenkt.In the FIG. 1 the header 20 is on a carriage 60, which serves to support the header 20 on the road. The carriage is composed of a frame 62 and a wheel 64. The frame 62 comprises a fan-spread rear portion 66 connected to a front portion 70 via approximately vertical struts 68 and wheel supports 72 disposed below the front portion 70, between which the wheel 14 is rotatably mounted about a laterally extending axis. On the rear part 66 facing side of the front part 70 is a carriage positioning device 74, which is a bag or bag-like, in the FIG. 1 having rightward opening, the underside extends obliquely backwards and down to the rear part 66 down. The carriage positioning device 74 is used for automatic alignment of the carriage 60 relative to the header 20 by a splitter tip 71 of the header 20 is received therein (s. FIG. 5 ). Rearward supports 76 support the back portion 66 of the rack on the ground. The wheel 64 is articulated in the illustrated embodiment about an approximately vertically extending axis of rotation 78 trailing steered on the frame 62.

Zwei an der Unterseite des unteren Querträgers 42 angeschweißte Konsolen 80 sind durch jeweils einen abnehmbaren Haltestift 82 mit außen an der rückwärtigen Oberseite des Rückteils 66 befestigten Haltern 84 verbunden. Die Haltestifte 82 erstrecken sich jeweils durch koaxiale Öffnungen in der Konsole 80 und im Halter 84. Weiterhin ist der obere Querträger 44 von zwei seitlich nebeneinander angeordneten, mit ihm verschraubten Konsolen 86 umschlossen, die je eine Aufnahmeeinrichtung 88 tragen. Zwei Streben 90 sind an ihrem vorderen Ende um eine horizontale, quer zur Vorwärtsrichtung verlaufende Achse 92 oben an der Rückseite des Vorderteils 70 des Wagens 60 angelenkt und liegen an ihrem hinteren Ende auf einer Aufnahmeeinrichtung 88 auf. Ein um eine horizontal und quer zur Vorwärtsrichtung verlaufende Achse 94 schwenkbar an der Aufnahmeeinrichtung 88 angelenkter Riegel 96 umschließt von oben her einen horizontal und quer zur Vorwärtsrichtung verlaufenden Stift 98, der am hinteren Ende der Strebe 90 befestigt ist.Two brackets 80 welded to the underside of the lower cross member 42 are connected by respective removable retaining pins 82 to retainers 84 secured externally to the rear upper surface of the rear portion 66. The holding pins 82 each extend through coaxial openings in the bracket 80 and in the holder 84. Furthermore, the upper cross member 44 of two laterally juxtaposed, with it screwed brackets 86 enclosed, each carrying a receiving device 88. Two struts 90 are hinged at their front end about a horizontal, transverse to the forward axis 92 at the top of the rear of the front portion 70 of the carriage 60 and are at its rear end on a receiving device 88. A latch 96 pivotally coupled to the receptacle 88 about an axis 94 extending horizontally and transversely to the forward direction encloses from above a horizontal and transverse pin 98 which is secured to the rear end of the strut 90.

Die Figuren 3 und 4 zeigen den Wagen 60 ohne Erntevorsatz 20. Hinter der Drehachse 78 ist am Vorderteil 70 ein sich horizontal und quer zur Vorwärtsrichtung erstreckender Träger angebracht, der ein mittleres, starr am Vorderteil 70 angebrachtes Element 100 und zwei sich dazu parallel erstreckende äußere Elemente 102 umfasst. An den Unterseiten der äußeren Elemente 102 sind sich vertikal und quer zur Vorwärtsrichtung erstreckende Warntafeln 104 befestigt. Endseitig tragen die äußeren Elemente 102 außerdem Beleuchtungsmittel 106 in Form kombinierter gelber Blink- und weißer Beleuchtungslampen.The FIGS. 3 and 4 show the carriage 60 without harvesting attachment 20. Behind the axis of rotation 78 is mounted on the front part 70 a horizontally and transversely to the forward direction extending support comprising a central, rigidly attached to the front part 70 element 100 and two parallel thereto extending outer elements 102. On the undersides of the outer members 102 are vertically and transversely extending to the forward direction warning panels 104 attached. At the end, the outer members 102 also carry illumination means 106 in the form of combined yellow flashing and white lighting lamps.

An den äußeren Enden der äußeren Elemente 102 sind weiterhin sich vertikal erstreckende Haltepfosten 108 fixiert, die jeweils eine Seitenplane 110 haltern. Am rückwärtigen Ende der Seitenplanen 110 sind Stangen 112 befestigt, die wiederum durch federbelastete Haken 114 trennbar mit dem Erntevorsatz 20 verbunden sind. Die Stangen 112 und Haltepfosten 108 sind insbesondere Vierkantrohre. Ein mit den Beleuchtungsmitteln 106 verbundenes Anschlusskabel 116 ist über einen Teil seiner Länge an der linken Seitenplane 110 befestigt, insbesondere sandwichartig zwischen zwei Lagen der Seitenplane 110 eingeschlossen, und trägt endseitig einen Stecker 118, der in eine passende Buchse 120 am Einzugsgehäuse 30 der Erntemaschine 10 einsteckbar ist.At the outer ends of the outer members 102 are further fixed vertically extending retaining posts 108 which each support a side curtain 110. At the rear end of the side panels 110 rods 112 are attached, which in turn are connected by spring-loaded hooks 114 separable with the header 20. The rods 112 and retaining posts 108 are in particular square tubes. One with the illumination means 106 connected connection cable 116 is attached over a portion of its length to the left side tarpaulin 110, in particular sandwiched between two layers of the side tarpaulin 110, and carries at the end a plug 118 which can be inserted into a matching socket 120 on the feeder housing 30 of the harvester 10.

Die äußeren Elemente 102 des Trägers sind um sich vertikal erstreckende Achsen 122 am mittleren Element 100 angelenkt und sind in der in den Figuren 2 bis 5 dargestellten Stellung arretierbar. Der Wagen 60 weist am Rückteil 62 klappbare Befestigungsmittel 124 zum Anbringen des Gestells 62 an den Unterlenkern 128 (s. Figur 6) eines Traktors 126 auf. Die Strebe 90 wird dann mit dem Oberlenker der Dreipunktaufnahme verbunden.The outer elements 102 of the carrier are articulated about vertically extending axles 122 on the central element 100 and are in the in the FIGS. 2 to 5 shown locked position. The carriage 60 has at the back of 62 hinged fasteners 124 for attaching the frame 62 to the lower links 128 (s. FIG. 6 ) of a tractor 126. The strut 90 is then connected to the upper link of the three-point recording.

Die in den Figuren 1 und 2 dargestellte Konfiguration wird zum Transport der Erntemaschine 10 mit dem daran angebrachten Erntevorsatz 20 auf einer Straße hergestellt. Der Bediener fährt die Erntemaschine 10 mit dem Erntevorsatz 20 an den Wagen 60 heran, so dass die Wagenpositionierungseinrichtung 74 im Zusammenwirken mit der Teilerspitze 71 die gewünschte Ausrichtung zwischen Wagen 60 und Erntevorsatz 20 bewirkt. Die Haltestifte 82 werden eingeführt und die Strebe 90 wird verriegelt.The in the FIGS. 1 and 2 The illustrated configuration is made to transport the harvester 10 with the header 20 attached thereto on a road. The operator drives the harvesting machine 10 with the header 20 to the carriage 60, so that the carriage positioning device 74 in cooperation with the divider tip 71 causes the desired alignment between the carriage 60 and header 20. The retaining pins 82 are inserted and the strut 90 is locked.

Zur einfacheren Bewegung der Anbringung des Wagens 60 am Erntevorsatz 20 könnte oberhalb des Vorderteils 70 ein einzelner Hebel vorgesehen sein. Der Hebel wäre an der Vorderseite des Wagens 60 um eine horizontal und quer zur Vorwärtsrichtung verlaufende Achse angelenkt. Oberhalb der Achse sind zwei Stangen am Hebel angelenkt, die an ihrem anderen Ende mit einer zusätzlichen Konsole verbunden sind, die jeweils an einer Strebe 90 befestigt ist. Zusätzlich ist an der Unterseite der Streben 90 ein Seil angebracht, das über Umlenkrollen mit den federbelasteten Haltestiften 82 verbunden ist und zu ihrem Ent- und Verriegeln dient. Dadurch wird es möglich, durch eine Bewegung des Hebels die Streben 90 auf die Aufnahmevorrichtung 88 zu legen und gleichzeitig die untere Verriegelung mit den Bolzen 82 zu schließen. Analog können durch eine Bewegung des Hebels 2 in umgekehrter Richtung die Streben 90 nach oben verschwenkt und die Bolzen 82 gelöst werden.For easier movement of the attachment of the carriage 60 on the header 20, a single lever could be provided above the front part 70. The lever would be hinged to the front of the carriage 60 about a horizontal and transverse to the forward axis. Above the axis, two rods are hinged to the lever, which are connected at its other end with an additional bracket, which is fastened respectively to a strut 90. In addition, a rope is attached to the underside of the struts 90, which is connected via pulleys with the spring-loaded retaining pins 82 and serves to unlock and lock. This makes it possible, by a movement of the lever, the struts 90 on the receiving device 88 and at the same time to close the lower latch with the bolt 82. Similarly, by a movement of the lever 2 in the reverse direction, the struts 90 pivoted upward and the bolts 82 are released.

Der erfindungsgemäße Wagen 60 ist mit der Schutzeinrichtung ausgestattet, die sich aus den Warntafeln 104, den Seitenplanen 110 und den Beleuchtungseinrichtungen 106 zusammensetzt. Bei der Vorbereitung des Erntevorsatzes 20 zu einer Straßenfahrt sind demnach lediglich die Haken 114 der Stangen 112 an den Rückseiten der Seitenplanen 110 am Erntevorsatz 20 zu befestigen und der Stecker 118 in die Buchse 120 zu stecken; weitere Maßnahmen zur Anbringung der Schutzeinrichtung erübrigen sich.The carriage 60 according to the invention is equipped with the protection device, which is composed of the warning panels 104, the side tarpaulins 110 and the illumination devices 106. Accordingly, when preparing the header 20 for road travel, only the hooks 114 of the rods 112 are to be secured to the rear sides of the side panels 110 on the header 20 and the plug 118 is to be inserted into the socket 120; Further measures for attachment of the protective device are unnecessary.

Soll der Wagen 60 zum Erntebetrieb wieder vom Erntevorsatz 20 getrennt werden, wird der Erntevorsatz 20 durch Betätigung geeigneter Hydraulikzylinder der Erntemaschine 10 angehoben, um das Rad 64 zu entlasten. Dann werden die Haltestifte 82 abgenommen und der Riegel 96 nach hinten (in Figur 4 im Uhrzeigersinn) gedreht, um die Strebe 90 freizusetzen. Die federbelasteten Haken 114 werden abgenommen und der Stecker 118 aus der Buchse 120 gezogen. Die Erntemaschine 10 fährt dann nach hinten fort. Die Umrüstzeit für den Straßentransport bzw. Erntebetrieb ist somit relativ gering.If the cart 60 are to be separated again from the harvesting attachment 20 for harvesting operation, the harvesting attachment 20 is raised by actuation of suitable hydraulic cylinders of the harvesting machine 10 in order to relieve the wheel 64. Then the retaining pins 82 are removed and the latch 96 to the rear (in FIG. 4 rotated clockwise) to release the strut 90. The spring-loaded hooks 114 are removed and the plug 118 is pulled out of the socket 120. The harvester 10 then continues to the rear. The changeover time for the road transport or harvesting operation is thus relatively low.

Um zu vermeiden, dass der Bediener zur Befestigung am oder zum Abnehmen des Wagens 60 vom Erntevorsatz 20 die Fahrerkabine 18 verlassen muss, können zur Bewegung der Haltestifte 82 auch fremdkraftbetätigte Arretierungseinrichtungen vorgesehen werden, z. B. Hydraulikzylinder, die vom Arbeitsplatz des Bedieners in der Fahrerkabine 18 aus steuerbar sind. Der Riegel 96 könnte ebenfalls durch Fremdkraft oder über ein Seil von der Fahrerkabine 18 aus bewegt, zumindest gelöst, werden. Der Stecker 118 kann dann am Gestell 62 befestigt sein, während die Buchse 120 an einem benachbarten Halter am Einzugsgehäuse 30 angeordnet ist, so dass die elektrische Verbindung für die Beleuchtungsmittel 106 beim Ankoppeln des Wagens 60 selbsttätig hergestellt und beim Abkoppeln selbsttätig getrennt wird. Die Seitenplanen 110 könnten dann durch in sich starre Ausführungsformen ersetzt oder durch geeignete Zugmittel von der Erntemaschine 10 aus erfasst und gespannt werden.In order to avoid that the operator must leave the driver's cab 18 for attachment to or for removal of the carriage 60 from the header 20, for the movement of the retaining pins 82 also force-actuated locking devices may be provided, for. B. hydraulic cylinders that are controllable from the workplace of the operator in the cab 18 from. The latch 96 could also be moved by external force or via a cable from the cab 18, at least dissolved. The plug 118 may then be fixed to the frame 62, while the socket 120 is disposed on an adjacent holder on the feeder housing 30, so that the electrical connection for the illumination means 106 during coupling of the carriage 60 automatically produced and separated automatically when uncoupling. The side panels 110 could then be replaced by inherently rigid embodiments or be grasped and tensioned by suitable traction means from the harvester 10.

Falls sich der Wagen 60 nach der Ernte in größerer Entfernung von der Erntemaschine 10 befindet, kann er mittels eines Traktors 126 herangeholt werden (Figur 6), indem die Unterlenker 128 des Traktors mit den Befestigungsmitteln 124 verbunden werden. Anders als in der Figur 6 dargestellt, könnte ein Oberlenker einer Dreipunktaufnahme mit der Strebe 90 verbunden werden. Die nach hinten - in der Figur 3 nach rechts - einschwenkbare Anlenkung der äußeren Elemente 102 des Trägers um die Achsen 122 ermöglicht eine wesentliche Verminderung der Transportbreite.If the cart 60 is located after the harvest at a greater distance from the harvester 10, it can be fetched by means of a tractor 126 ( FIG. 6 ) by connecting the lower links 128 of the tractor with the fastening means 124. Unlike in the FIG. 6 illustrated, a top link of a three-point recording could be connected to the strut 90. The back - in the FIG. 3 to the right - pivotal articulation of the outer elements 102 of the carrier about the axes 122 allows a significant reduction in the transport width.
